@I created a dashboard with 3 datasources, I did left join of primary data source with other 2 giving project id as primary key global filter. When there is single value in project ID, the global filter is not getting applied to the rest of worksheets.

IF there are multiple values in the filter, I have to clear all the values, and then select the value, then the filters are applied.

Hi Diego, The audience will be using Tableau Reader, so refreshing data source is out of question. If i de-select filter and re-select also single selection does'nt work, only when multiple values are present, and i select one from those the filters are working as expected. if single value is there, it automatically gets selected to that value, even if i de select and re select that single value its not working.
